ISO 10993-23 In Vitro Skin Irritation Testing (Reconstructed Human Epidermis Models)
The ISO 10993-23 standard specifies the use of reconstructed human epidermis (RhE) models for in vitro skin irritation testing. This method evaluates a medical device’s potential to cause skin irritation, ensuring that it meets biocompatibility requirements before clinical trials and market release.
Reconstructed human epidermis models are synthetic tissues made from living keratinocytes, which closely mimic the structure of human skin. These models undergo differentiation into stratified squamous epithelium, providing a more accurate representation of the skin’s barrier function compared to traditional animal testing methods. The standard outlines detailed protocols for preparing and using these models in irritation assays.
The testing procedure involves placing the medical device under test (MDUT) in direct contact with the RhE model for a specified period. After exposure, the model is examined for signs of inflammation such as increased vascular permeability or histopathological changes. The results are then compared against control samples to determine whether the MDUT caused irritation.
Biocompatibility testing using ISO 10993-23 is crucial in ensuring that medical devices do not harm patients during use. By leveraging RhE models, manufacturers can perform rigorous preclinical assessments without exposing subjects to unnecessary risks associated with animal testing. This approach supports regulatory compliance and enhances product safety.
The standard also emphasizes the importance of selecting appropriate test durations based on the expected contact time between the MDUT and patient skin. For prolonged or frequent contacts, longer exposure times may be necessary to accurately assess potential irritation risk.
Using reconstructed human epidermis models aligns with global trends towards ethical alternatives in toxicity testing. The RhE model provides a reliable and reproducible method for evaluating the biocompatibility of medical devices, making it an essential tool in modern regulatory submissions.
At our laboratory, we employ state-of-the-art equipment and highly trained personnel to conduct ISO 10993-23 tests with precision and accuracy. Our services include thorough documentation of each test run, ensuring that all data points are captured for comprehensive reporting.
